1.2.1.2 Designation of the signal type in the variable name
Theinputsand outputs of theLenzefunctionblocks eachhaveaspecific signaltype assigned.These
may be: digital, analog, position or speed signals.
For this reason, each variable name has an ending attached that provides information on the type of
signal.
Signal type Ending Previous designation
analog _a (analog)
H
digital _b (binary)
G
phase-angle difference or speed (rot.) _v (velocity)
F
phase-angle or position _p (position)
E
Tip!
Normalizing to signal type phase-angle difference/speed: 16384 (INT) 15000 rpm
Normalizing to signal type analog: 16384
100 % value under [C0011] = N
max
Normalizing to signal type angle or position: 65536 1 motor turn
Examples:
Variable name Signal type Variable type
nIn_a Analog input value Integer
dnPhiSet_p Phase signals Double-integer
bLoad_b Binary value (TRUE/FALSE) Bool
nDigitalFrequencyIn_v Speed input value Integer
1.2.1.3 Special handling of system variables
System variables require special handling, since the system functions areonly availablefor the user
as I/O connections in the control configuration.
In order to be able to access asystem variable quickly during programming, thevariable name must
include a label for the system function.
For this reason, the name of the corresponding system block is placed before the name of the
variable.
Examples:
AIN1_nIn_a
CAN1_bCtrlTripSet_b
DIGIN_bIn3_b
